Question

I have this ASP code:

 <ext:GridPanel ID="grid">
                <ColumnModel runat="server">
                    <Columns>
                        <ext:RowNumbererColumn />
                        <ext:Column Align="Center" ColumnID="Type">
                        </ext:Column>
                    // closing tags

I want to get the columns object. I’m trying this:

var typeCol= this.grdResourceState.ColumnModel.Columns.Where(column => column.ColumnID == "Type"); // this works
var typeColRef= FindControl("grdResourceState.ColumnModel.Columns"); // this is a null

What do I do to make FindControl be able to search control children?

Answer 1

You should assign an id to the ColumnModel control and then retrieve if. Once you got it you can access the children controls:

<ext:GridPanel ID="grid">
                <ColumnModel runat="server" id="someId">
                    <Columns>
                        <ext:RowNumbererColumn />
                        <ext:Column Align="Center" ColumnID="Type">
                        </ext:Column>
                    // closing tags

Then:

var typeCol= this.grdResourceState.ColumnModel.Columns.Where(column => column.ColumnID == "Type"); // this works
var typeColRef= FindControl("someId");
